AUTOMATIC PAPER-CUTTING- MECHANISM.

Specification of Letters 1atent.

Patented Dec. 19,1916.

Application filed March 6, 1916. Serial No. 82,369. I

To all whom it may concern: Be it known that I, AARON H. HANDY,

a citizen of the United States, residing at Kansas City, in the countyof Jackson and State of Missouri, have invented certain new and usefulImprovements in Automatic Paper-Cutting Mechanism, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame. i

The invention relates to mechanism for containing rolls of wrappingpaper and cutting various lengths from the roll as required.

It is essential that the roll of paper be journaled in suitable framesso that it will roll freely without tearing the paper, and that asuitable brake be provided to check the rolling of the roll when thedesired length of paper has been drawn therefrom so that the roll willstop and not unwind more paper than is drawn from the roll. Aconstruction that will admit of employing sheet metal for the cuttingknife, and provide for the mounting of a plurality of rolls in one frameis also very desirable.

The present invention seeks to provide an improved mechanism, forsupporting rolls of paper and automatically cutting desired lengths ofpaper therefrom, the features of the invention relating moreparticularly to certain improvements in the mechanism of the machineembodied in United States Patent No. 1,159,837, which was issued to theapplicant Nov. 9th, 1915.

A futher object of the invention is to provide a suitable adjustableresilient brace that will act direct upon the surface of th roll ofpaper.

A still further object of the invention is to provide for the mounting.of plural rolls of paper and serving them byxa single knife constructedof thin sheet metal and to employ an intermediate rest and stop for thelmife so that it will not spring and tear the paper.

A still further object of the invention is to provide an improved formof brake upon the small roll near the knife so that the paper when drawnfrom the mechanism rapidly will immediately stop when the drawingtension ceases and no more paper will be drawn than is desired. j i

With these and other objects in View the invention consists in thefeatures of construction, shapes, combinations and arrange ments ofparts hereinafter set forth, illustrated in the accompanying drawingsand more particularly pointed out in the appended claims.

In the drawings: Figure 1, is a view of the improved mechanism inelevation, arranged for and containing plural rolls of paper. Fig. 2, isa sectional view of the mechanism takenon line aa of Fig. 1. Fig. 3, isa fragmentary enlarged sectional View taken on line 12-42 of Fig. 1.Fig. 4 is a fragmentary enlarged sectional view taken on line c0 ofFig. 1. Fig. 5, is a fragmentary enlarged view. Fig. 6, is a fragmentaryenlarged view. Fig. 7 is a view of the mechanism in elevation, arrangedfor and containing a single roll of paper.

The base 1 is preferably of rectangular shape. as shown and of woodbecause of inexpensiveness, the end frames 2 and 3 and the intermediateframe 4 being secured to the base by screws 5 and extending upwardtherefrom, the journal boxes 6 being preferably integralwith therespective frames and open upward so that the rolls of paper 7 may beplaced with the journals 8 resting in r the boxes as shown and removedtherefrom without manipulating any part of the mechanism.

Secured to the base 1 and opening upward and provided with the flanges 9along the upper edge thereof is the channel shaped guide 10, the flangesextending toward each other and then projecting downward in the form ofteeth 12, forming a trackway be tween the toothed flanges and the bottom13 of the guide for the spring 14. vThe spring 14 has a wide portion 15which rests upon the bottom 13 at the end 16 thereof, and upwardlyinclined integral pawls 17. which engage the teeth 12, the spring beingfree to slide along the channel shaped guide 10 when the end 18 thereofis pressed downward and the pawls released from the teeth, the tensionofthe' spring produced by the end 19 pend on the swiftness with which thepaper is withdrawn from the roll, and that when gagement ,with,thetjeeth 12 and thespring:

will remain in this position untilreadjusted, the shape of the springproducing m'oie brake tension when the roll is of full: size than whenthe paper is'morene arly removed, this being desirable asthe more paperthe more weight and the greater the inertia that must he checked andstopped. U I The ro fjp p ri is WQ d l i t n ne-2. h nspro dea h"p j jouial'si 8 to fit and revolve freely in the i rii vbb ffia. a .s a.

The curved sheet metal guide 29 separate'd from the flat sheet metalguide only 7 by the sheet of' pap 'er 11 and is'cprovided with thes1et20.; hrough which the pa er is threaded, the side of the guide 29 being'Q HrYd it 5 t V6 he 6 6 2 2161112 e de are bfl e h e fi g and ream, abral te' as hereinafter will appear. v The arm '36 is secured to theflat sheet metal guide 35"i11tei 'mediate,the arms 30 ana;, i pivotedinthe bifurcated jaw 37 at 385 se that the end 39 thereof will bear in evje t eQi he -th r s an 36 ir in the extreme upward pesit'ioh as w ll oiip' il oin thQd 'S' -I' of the p iatien, hereinafteif, the jaw" 37'Being s'ecu"red to the frame tie piece l byae integral belt 2.;t1ie ebeamin se fl to l d fiafiies 2 and e by the grammes, The are 3 or. t e-prpos QS Pii 2 ne theifl'it f? lguide fidthe lattenservihg also o kni brfr e bi n whentheesired ,ie 'gjh has srd ei gnit -le s leng s a insemen-131511 mm long rolls" fo'r' wade paper ward n'witlidiawn aeaiteeIran 7; the arin ber and inconnection with the mounting of two 1 or more.rolls under the same knife, it being desirabl'e'under certainconditions to mount several rollsTunderfthe same knife especially whenthe paper is of a narrow width. illhe paper 11 is wound upon the roller21 and placed with the journals 8 in the boxes 6 after which the paperis threaded over the roller 23 and under the curved portion 25 of thecurved sheet metal guide 29until the slot therein 20 is reached; thepaper passing upward through this" slot and then outward betweenftheportion of the curved sheet metal guide 29' and the flat sheetmetal'guide knife 3 5 the paper in'normal position always" protrudingfrom the guidessufi'iciently to allow of gripping it to withdraw fromthe roll? the normal position of the guides and sifpporting armsandpaper being illustrated in Fig. 2. e V

After the severed the-mechanism immediatelyassumes the position shown in Fig.- 2 and the paper is eiten'ded as;il'lu'strated in this View, it being obvious that the aper; is always ina position to allowj o'f, gripping it by the hand and that but aninstantis required to withdraw and sewer any desired length of thepaper. Thiraihi 2 and 3 are each offset and extended outward at 17 inorder to secure a -greaterdistancebetweenflthe frames and admit or theguides 29 and'35 being extended to agreater width, this fe'atu'reserving to allow thepaper to be withdrawn at a considerable' angle from?a right angle from the axis of the roll 7, so that theoperator willnotbe reqiiired tonotice whether the paper is. drawn'at alright"anglefrom therolls; it heing obviousthat the person desiring wrapping paperis usually in a hurry and will drawand cut the paper without looking ator thinking or thepaper cutting mechanism or the-roll'of paper, the mindbeing occupied by (aheemaaeis; c
